That is what a typical consumer desktop would want (Torrenting aside). http://en.wikipedia.org/wiki/File:ADSL_frequency_plan.svg If you're running a business, they have options where the bandwidth is symmetric. That means the download and upload are closer in value to one another. That is more suitable for some kind of server, like a web server. Where I live, I don't know exactly what standard they use for that. http://en.wikipedia.org/wiki/Symmetric_Digital_Subscriber_Line http://en.wikipedia.org/wiki/Digital_Subscriber_Line I expect the two adverts you're quoting above, are both ADSL. ADSL can go as high as about 24Mbit/sec, in cases where the latest standards are used, and the telephone company is comfortable with the extended spectrum needed on the lines. I'm still on the "8Mbit or less" standard here. I think the telephone company here, will only roll out that kind of service, as part of some kind of TV downloading feature ($$$ per month). http://en.wikipedia.org/wiki/Asymmetric_Digital_Subscriber_Line_2_Plus With the latest trends to capping the total bandwidth usage to ridiculous levels, it really doesn't matter what the max transmission rate is. You can easily use up your monthly allowance in a hurry. For example, here, I expect to be moved from 200GB/month to 60GB/month, with no reduction in price at all. If I were watching TV via the Internet, I'd burn that up in no time. Paul

Various flavors of xDSL acronyms with ADSL being preponderant in US, higher upload constraints on primary intended download usage (haven't exactly looked at Seoul's infrastructure). Basically, a connection created by a modem pair enabling high-speed communications (some would additionally emphasis for their modem, and not something one buy off fleabay for $19), or everything between and within constraints of wire guage and that relational distance to the IP's mutiplexer. I'd hazard that 6M is within full operable xDSL specifications and the 2M is a subset of shaping - tiered or limited characteristics for plans and business models at fifty-times a cost thruput over analog modems (what the ISP's pay for that cost is apparently not a subject any if at all readily care to discuss). I'd also think to stress a cost of fleabay -if- within constraints of wire guage & etcl, especially in lieu of such dedicated bases for customer service, such as Verizon contracts out to India or Pakistan;- it's where I was energetically told that if I didn't buy their modem or know precisely what I was doing with another, I could damage the "networks".
